That Dent in Your Milk Jug? It’s Smarter Than You Think. 🥛 Most people overlook the small dent on plastic milk jugs, assuming it’s a flaw—but it’s actually a clever design feature with several important functions.

🔹 Pressure Control:
The dent acts as a “flex zone” to handle the pressure from the heavy liquid and temperature changes, preventing bulging, leaks, or cracks.

🔹 Shock Absorption:
Drop the jug? The dent works like a tiny airbag, absorbing impact and reducing breakage.

🔹 Less Plastic, More Strength:
Like an architectural arch, the dent allows manufacturers to use less plastic while keeping the jug strong—saving money and cutting waste.

🔹 Easier Recycling:
It creates a weak point, making the jug easier to crush and more efficient to process.

So next time you pour a glass of milk, remember: that little dent is a quiet feat of engineering, making your jug safer, greener, and smarter.
